Abstract
An extendible, round robin, local area hub station network includes: at least two round robin hub station segments coupled so as to form a ring-shaped hub station segment signal path. One of the two hub station segments includes a master hub station segment adapted to provide control signals, such as electrical or optical signals, on the ring-shaped segment signal path to transfer control of round robin polling over the hub station network between any two hub station segments in the hub station network. The hub station segments are also mutually coupled by a signal bus. Likewise, a method of round robin polling in an extendible, round robin, local area hub network includes the steps of: signaling a request for control of round robin polling over the hub station network from at least one of the at least two hub station segments in the hub station network to the master hub station segment, and transmitting a signal from the master hub station segment transferring control of round robin polling over the hub station network between any two of the at least two hub station segments.
